Comment (by kencu):

 blacklisting clang < 800 with compiler_blacklist_versions appears to do
 it. That forces mavericks to call in clang-4.0, which supports
 thread_local.

 `portconfigure.tcl` should be updated at some point soon to fall back to
 clang-5.0 instead though, I think -- that's what the `cxx11 1.1` portgroup
 calls in, so might as well be consistent.
